To all 'u1/wm z' may concern: Be it known that I, Hona'ro G. GILLMon, a citizen ofthe United States, residing at Bath, in the county of Sagadahoc, State of 5 Maine, have invented certain new and useful Improvements 1n the Means of Forming Rail-Joints, of which the following is a specification, accompanied by drawings.

This invent-ion relates to rail joints and one of its objects is to so form such joints as to eiiiciently support the rail ends and overcome the tendency to vertical movement of 'one rail end relative to the other as the wheels pass.

'vAnother object is to provide for extra at the joints by additions to the mg of such joints, making use of the old parts; and to so combine the parts that the stresses will be distributed amonof them,

under all conditions of loading the joint, so that each part will take its `portion of the f working stresses.

Other objects are to el'ectually lock a porthe nuts securing the fish bars in. position against turning upon their lbolts and to provide etlieient means to prevent that movement of the rails as a whole known Yas creeping. A

.Further objects of the invention will hereinafter appear; and, to these ends, the inventionconsists of a rail joint for carrying out .the above objects, embodying the features of. construction, combination of elements and arrangement of parts having the general inode of operation as hereinafter described and Vclaimed in this specification and shown in the accompanying drawings, in which:

Figure 1 is a side elevationof a joint embodyi'ng the invention. Figs. 2 and 3 are sections at the planes indicated by and (y y) respectively, in Fig. l. an are sections illustrating m J ified forms of Fi 6 is a view illustrating the method of l ing the. nuts against slackening. A

Similar letters refer to similar parts throughout the several gures.

(a) represents the meeting ends of the rails; (5) angleor' fish bars; (c) a base plate.

. (d) represents a clamp or chair, (e) the clamp or' bolts securing the sh bars and.

and (j) the nuts lon 'these bolts.

v rails, the

joints embodying the invention.4

igageinent of the fiange (g) represents a packing piece, preferably of wood or other compressible material, and

a 4 chair secured in position by extended ends of the bolts (e) and nutsl (70)* 6o screwed thereon. Thev chair (72;) has a baseI (Z) to4 engage with under surfaces of an edge of the base plate (c) and downwardly projecting stiiening projecting flange (n) -from its upper edge, and the clamp or chair (d) has a base (o) to engage with the surface of the opposite lower edge of the base plate (c), and is also provided with downwardly projecting stifliening (p). The downwardly projecting portions (m) andV (p) of the clamp and Vcha1r are pierced with holes to receive the bolts (g) to draw these toward one another after the n uts (le) have been set up on the bolts (e)l to draw the-chair (it) into position. f

' (fr) represents spikes or screws travers-iA ing notches in the sh bars and holes in the base plate for securing the joint to the ties or sleepers (s).

(t) represents grooves inthe ishbar at that side of the joint at Whichthe clamp or rib on the clamp or chair to engage with these grooves.

(o) is the hole in the fitted between the fish chair y In making up the joint the base plate is laid underneath the meeting ends of the. angle or lish bars (b) placed in the usual manner and the clamp or chair (al) packing material bar (b) and the (m) and an `inwardly chair (d) is applied and (u) a corresponding y and v*the bolts (e) placed in position and these parts drawn into place by setting up the nuts (f) upon the bolts (e). This causes the base plato (c) and the fish bar h) to be clamped firmly upon the base anges of. the rails between the base (o) and the body of (d) and at the same time draws the rib (u) of (al) into the groove (2f) in the fish bar (5). The purpose of this is to provide for transmitting stresses to (d) b shearing stresses fish bar Si?) and the chair more near y as one piece than case were friction' alone,

(al) shall act would be the assisted by the enthe rail bases with (d), relied upon. The packing material is their placed in position at the side of the joint opposite to the chair or clamp (al). The chair (it) is then placed in position with the extended. ends y in the rib (u) so that the of the fish bar and lill nospam 2. A rail joint, including, in combination I with the rails, fish bars and bolts and nuts securing the same, a packing of compressible material constructed to engage with and have partially embedded therein the nuts upon said bolts whereby said nuts are prevent-ed from turning .upon said bolts, and means for drawing said packing into and retaining the same in position, substantially as described.
